The preparations for public opinion include: (1) Dan's calligraphy "Chen" was placed on silk books, and the book was placed in the stomach of fish; (2) bonfires and foxes. Actually, in the name of ghosts and gods, they called on the defenders to prepare for the uprising with Chen Sheng. ?

Launching an uprising is divided into three steps: (1) Seize the opportunity of "drunken commandant", stimulate commandant to fight guangwu, and make defenders stand on his side; (2) Boldly "killing two commandos" removed the stumbling block of the uprising and caused trouble again, leaving no room for the garrison soldiers to hesitate to retreat; (3) carry out general mobilization, explain the desperate situation, and point out the future of narrow escape ~
